A pickup truck tailgate supports a crate (Wc = 900 N), as shown in the figure. The tailgate weighs W, = 270 N and is supported by two cables (only one is shown in the figure). Each cable has an effective cross-sec- tional area A = 11 mm². (a) Find the tensile force T and normal stress o in each cable. (b) If each cable elongates 8 = 0.42 mm due to the weight of both the crate and the tailgate, what is the aver- age strain in the cable? Wc = 900 N de = 450 mm H = 300 mm Truck Cable dr = 350 mm L=400 mm Crate F = 450 N Tail gate WT = 270 N h= 275 mm| A pickup truck tailgate supports a crate (Wc = 900 N), as shown in the figure.
